Expiations Are Not Divided

Question: A collision occurred between two cars. There were two people in the other car, and one of them died. According to the police and traffic report, the degree of fault was 30 percent for the owner of the first car and 70 percent for the owner of the other car.
Regarding the expiation, does the owner of the first car have to fast for two full months, or is it based on the percentage of fault, as is the case with blood money?

Answer: If two or more people are involved in an accidental killing, each one has an independent expiation; because expiations are not divided, as the scholars have stated.
